Prisoners is a 1929 American sound part-talkie film produced by Walter Morosco and directed by William Seiter for First National Pictures. In addition to sequences with audible dialogue or talking sequences, the film features a synchronized musical score and sound effects along with English intertitles. The sound was recorded via the Vitaphone sound-on-disc process. The screenplay was written by Forrest Halsey, based on the novel by Ferenc Molnar. Lee Garmes was the cinematographer.

The film stars Corinne Griffith, James Ford, Bela Lugosi, Ian Keith, and Otto Matiesen. Lugosi, in his first talkie, played Brottos, the owner of a Vienna nightclub. Lugosi was very happy that his first sound film was set in Hungary (where he was born) and that the story was based on a Ferenc Molnar Hungarian novel. While Lugosi was off filming "Prisoners", he was temporarily replaced in the San Francisco "Dracula" stage play by one Frederick Pymm (who normally played Butterworth, the attendant).

The relatively short segment with dialogue (most of the film has intertitles with music) picks up with the climactic trial sequence. Critics stated "Bela Lugosi makes a very European villain", but were disappointed that Griffith's character is sent off to prison at the end of the film while a "cold-blooded murderer (in one of the subplots) is kept from receiving his just punishment". Corinne Griffith (who was married to producer Morosco) later went on to become a movie producer herself, as well as a very successful novelist.
